I'd give Pace a call, and see if the SX-80, 90, or even 100 will work with it (nozzles changed to reduce clogs; don't know about the connector pin-out). Hopefully one of these will work with it, and you find a used one on eBay (i.e. saw an SX-80 w/o nozzle for $39 starting and no bidders).
Otherwise you'll have to wait for an SX-70 to show up at a decent price or unload the MBT and get something else. For a station, you could consider a
ZD-985 or a self-enclosed gun version such as the
S-993A (quite a bit cheaper). There are threads on both of these in the forum if you search.
FWIW, if you're not doing a lot of desoldering marathons, you would be better off just using a decent manual desolder pump (i.e.
Engineer SS-02) and some decent desolder wick/braid.
You'll need decent wick regardless (Chemtronics, MG Chemicals, Techspray, or Multicore [aka loctite/Henkel]). Genuine Goot is good stuff too, but as it's so counterfeited, best to skip it unless you're ordering directly from Japan.
BTW, selecting your country in your user profile will help others with links, particularly those regarding pricing & A/C input voltages for powered equipment.
